I did not have enough time to fix savegames on DC, so this release has no savegame support. There are also other issues such as random hangs that will need to be investigated (these kinds of issues may not be DC-specific).
For SCI0 games FreeSCI 0.3.5 is still your best bet. If you want test some early SCI1 games (SQ1VGA, SQ4, LSL1VGA etc), then you could try this new binary.
It might not be very useful without savegame support, but I decided to release it anyway, as some people may want to try it out regardless.
